Ok my tier list and thoughts on every character, which will also answer your other comment:
S-tier:
1. Mileena (she has 2 sai's, one straight with good knockback and one homing with weak knockback, so I think it's balanced imo)
A-tier:
2. Scorpion, with his airgrab he has some devious unbreakable setups that can combo into an huppercut if you cancel the airgrab into a waveland. Also I know his cpu really spams teleport punch a lot but the ai for the game is really a mess of a code and I honestly don't know why he does this sorry.
3. Liu Kang, I think his cooldowns are pretty short but it is coherent with identity as a rush down character.
B-tier:
4. Subzero, I honestly don't think he's bad because he has really good neutral but when you don't have your opponent in the corner his combos are not that good.
5. Raiden, by far the character with the most fun combos imo, but they mostly all start with an huppercut which can be difficult to land. He has pretty bad combo starters in general. Also his grab can be used for some unbreakable setups if you cancel into it from an heavy punch or something.
C-tier:
6. Kitana, by far the worst character imo. She's the first character I made and she's very simple and kind of outdated because of that. I think she can work if you play her really really defensive but it is a bit boring.
